There's a lot of cat owners who rent. Most of them probably don't have permission to have their cat but do anyway. So.. Give yourself an edge by obtaining permission for a cat in your apartments and advertise them accordingly. Scream "cat friendly" from the rooftops and make sure the listing is ticked as "pet friendly" to capture those who use search filters. When I have listed my Marrickville 2 bedders for lease, they've either been the ONLY, or one of only TWO apartments listed for lease in Marrickville at that time where cats were considered. I have never had a vacant day (in over 1,000 tenant days) and have had applications from cat owners before the first open in each case. Tenants with a cat may pay a premium for somewhere they are allowed to keep fluffy You widen your tenant pool, catering to those with and without cats Cat-owning tenants will have few other places to go, making them more likely to stick around and look after the place as they're on to a good thing There's little reason not to obtain permission for a cat If you are worried about damage a cat might cause, all I have to say is: babies and toddlers One final tip. On my most recent rental listing, I was pretty obnoxious and literally put, in huge writing "CAT FRIENDLY" on the main image so people scrolling through would see it as they skimmed through photos. I didn't know if I'd be allowed to use a photo with text overlaid. Seems I was. Even if most renters didn't have cats, obnoxious text on an image is a nice way to grab attention. Whatever it takes..
